computer's freezing...

[PSUstoekl]

well, my computer keeps freezing on me, but i've noticed it only happens whenever I'm playing a game. within painkiller it seems to happen the most.

what'll happen is the game will unexpectedly freeze completely, with no ctrl-alt-del possibility (the caps lock light doesn't even work), and a horrible squelching sound comes from the speakers. i have an x-fi card, does that make a diff?

also, it might be my RAM?

Antec 450W PSU (w/ PCIe output)
OCZ Performance 3200 1x2GB DDR
evga 7800GT

currently, my GPU temp is 36 Celsius. Under full load, it goes up.

Now, this problem only seems to occur in certain games. In CoD2 it's never happened, but it happens frequently in Painkiller and infrequently in FEAR. Also, I've gotten it once or twice in Half Life 2, but both times it crashes to desktop.

Can you look in event viewer and see if anything shows up?
